当我的 ubuntu 更新了一些 r-cran 软件包时，出现了“HAVE_UINTPTR_T redefined”的警告。这个警告重要吗？有人可以解释这个宏吗？我还在一些 python 标头中找到了它。

In file included from /usr/local/include/RInside/RInside.h:26:0,
/usr/local/include/RInside/RInsideCommon.h:50:0: warning: "HAVE_UINTPTR_T" redefined [enabled by default]
   #define HAVE_UINTPTR_T
 ^

In file included from /usr/share/R/include/R.h:81:0,
             from /usr/local/lib/R/site-library/Rcpp/include/Rcpp/r/headers.h:52,
             from /usr/local/lib/R/site-library/Rcpp/include/RcppCommon.h:29,
             from /usr/local/lib/R/site-library/Rcpp/include/Rcpp.h:27,
             from /usr/local/include/RInside/RInsideCommon.h:38,
             from /usr/local/include/RInside/RInside.h:26,

/usr/share/R/include/Rconfig.h:23:0: note: this is the location of the previous definition
 #define HAVE_UINTPTR_T 1

这确实是 R 3.4.0 的一个新警告，但现在在提交到 master 分支后它被抑制了：
